manager
package should not depend oncontainer/docker
(or any other specific container runtime) in principle.doing so will drag in unnecessary dependencies into kubelet. (example when dockershim is removed, this dependency will drag in docker/docker transitively into kubernetes vendor/ directories)
DockerInfo and DockerStatus methods are not really needed. Just use the public methods from the
container/docker
package
